Kalibreeritus

Kalibreeritus is a term used in metrology to denote the state of a measurement instrument, system, or dataset after calibration against a defined reference standard. In this sense, kalibreeritus describes both the act of calibration and the resulting condition in which measurements are aligned with traceable standards, with an associated uncertainty bound. The term implies that the instrument's readings are corrected for systematic bias and that ongoing traceability to higher-level references is maintained.

Etymology: kalibreeritus is formed from kalibreerima (to calibrate) and the nominal suffix -itus, indicating a state or condition. It is used in several European languages and international technical documentation as a compact label for calibration status.

Scope and usage: Kalibreeritus applies to diverse devices, including mechanical gauges, electronic sensors, analytical instruments, and software measurement routines. It also encompasses calibration certificates and databases that record reference values, uncertainties, and validity periods.

Process: Achieving kalibreeritus typically involves selecting appropriate reference standards, performing comparative measurements, computing correction factors or adjustments, and documenting results. A calibration certificate should specify the instrument, the reference standards, the measured deviation, the reported uncertainty, and the recommended recalibration interval. For regulated environments, kalibreeritus is linked to requirements for traceability, documented evidence, and management review.

Maintenance and limitations: Kalibreeritus can degrade over time due to wear, drift, temperature changes, and environmental factors. Regular recalibration and proper handling are essential to maintaining calibrated status and ensuring measurement reliability.
